Carlos Quentin returns to Chicago for treatment on sore left foot

Sox left fielder won't be available until Tuesday at the earliest

TORONTO — The strange case of Carlos Quentin's ailing left foot took two twists Sunday but ended in the same result: The White Sox slugger won't be available until at least Tuesday.

Quentin returned Sunday night to Chicago to undergo shock wave therapy, a non-invasive method of treating foot pain. Quentin has been bothered since April 28, when he stepped on a base and felt discomfort that became increasingly painful.

Quentin, who hit 36 home runs last year but is hitting just .187 over his last 21 games, took a cortisone shot Tuesday after being scratched from the lineup.

The injection worked on his left heel, the original location of the discomfort. But since then, the pain has transferred to the midfoot area.

Before the game, bench coach Joey Cora -- managing his second game while Ozzie Guillen attended his son's graduation -- thought Quentin would return to Chicago soon. That was before Quentin, who spent several hours in the training room before Sunday's game, took some swings, according to a team spokesman.

But after the game, Cora said Quentin was headed to Chicago for more treatment.

The Sox do not believe Quentin aggravated the injury by pinch-hitting Wednesday and playing all nine innings Friday on the Rogers Centre's artificial turf. He could return as soon as Tuesday, Cora said after Sunday's 8-2 loss.

Nevertheless, the Sox will play short-handed in Monday's finale against the Blue Jays, with outfielder Brian Anderson scheduled to rejoin the Sox on Tuesday after completing a minor league rehabilitation assignment.
